Letters Patent No. 85,581, dated .Tamm/ry 5, 1869 IMPRovnMENr 1N coRN1=LANTERs-- The Schedule referred to in these Letters Patent and making d' the same.

To all whom it ma/y concern:

Be it known that I, WILLIAM B. GOODWIN, of Kinmundy, inthe county of Marion, and State of Illinois, have invented a new and useful Improvement in Corn- Planters; andI do hereby declare that the following is a full, clear, and exact descri tion thereof, which will enable others skilled in the a to make and use the same, reference being had to theaccompanyn'ng drawings, forming part. of this specification.

Figure 1 is a vertical longitudinal section of my improved corn-planter, taken through the line :1r-x, g. 2.V

Figure 2 is a top or plan view of the same.

Similar letters of reference indicate corresponding parts.

My invention has for its object to improve the conto make them more simple in construction, more effective in operation, and less liable to get out of order; and n It consists in the construction and combiuatiori of said parts, as hereinafter more fully described.

AA is the frame-work of my improved planter.

B is the axle, which revolves in' bearings in the ame A. Y

Care the wheels, one of which -is rigidly attached D are the plows, that open the furrows to receive the corn. The rear parts f the plows are made hollow or tubular, and are provided with a spreader, (not shown in the drawings,) to spread the corn as it drops to the ground.

E is the dropping-plate or bar, by which the corn is dropped, and which extends entirely across the frame A, so as to drop the corn from both hoppers at the same time.

The bar E is4 provided with projecting armsor lugs, e', to receive the wheel bywhich the said bar is oper- F isa gear-wheel, placed upon the axle B, in such a. manner that it may be movedback and forth to throw gear-wheel G may mesh intothe teeth of the geariy wheel F. 4

Into the teeth of the gear-wheel G, also mesh the teeth of 'the gear-wheel H, attached to the .markershaft I.

The gear-wheel H is provided with inclined projections, J formed upon or attached to its sides, which strike against the arms e of the dropping-bar E, to movev the said bar `back -and forth at the proper time to drop the corn.

The shaft I revolves in bearings attached to the frame A, and to its projecting ends are attached disks or small wheels, K, theouter sidesof which are grooved to receive the marker-arms L, which are secured in place by set-screws, so that the length of the arms L may be adjusted at pleasure, according to the depth at which the plows are to run inthe ground.

The various operating-parts of themachine must be so constructed and arranged that the marker-arms L may come to the ground at the right time to mark the exact spots where, the hills have been planted.

I claim as new, and desire to secure by Letters Patent- 1. The gear-wheelH, constiucted substantially as herein shown and described, inA combination witlrthe marker-shaft I and dropping-bar E, and operated from the axle B by the gearing F G, as and for the purpose set forth.

2. The combination of the adjustable marker-arnis L and grooved supporting-disks or wheels K with the marker-shaft I, substantially as herein shown and described, andfor the purpose set forth. h
